In the case of Light of my life the guy does everything himself. He does it because it's his passion, he releases it himself for free, constantly updates the news, and every time he releases an update it's hours long and a full chapter. You think he is milking good for you, that is your opinion and you are entitled to it.
But he has never bullshited, has never lied, is active in the forum and is a generally nice guy who will answer your complaints in person and with respect. Contrast that to other devs who don't give a shit about you. As for DmD I agree it's a good game, one of my favorites. Yeah seeing as it is a collaborative effort it has more content that LomL. That does not mean I can't enjoy each game for what it brings to the table. Hell even though I first I could not stand the models LomL used it grew on me.
